ALBERT E. MQORHEAD, OF OAKLAND, CALIFORNIA.

PNEUMATIC DEVICE FOR GOLTJECTING AND BEE/ DYING DUST.

Application filed October 1 9,

To all whom it may concern:

Be it known that I, ALBERT E. Moon-man, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certaiiv new and useful Improvements in Pneumatic Devices. for Collecting and..Ren1oving Dust, of which the- :t'ollowing' is a specification.

My invention= relates to an improvedpneumaticdevice for collecting and removing dust from dwellings, ofiices or other inhabited inclosures and. from furniture and eiiects-in such places.

The objects of my invention are to rapidly and effectually remove dust that collects in homes, ofiices and other places, without escape and diffusion of the dust in the inother devices not .pro'vided with induced air currents, and in a means to loosen. concentrate and remove the dust.

This invention consists of a device or apparatus for manual use.

A case open at low tubes that are in a degree flexible and surrounding these tubes circular brushes that extend beyond the ends of the tubes to agitate and loosen the dust which, by an induced air current. is drawn into the tubes and collected in a chamber in the casing from which leads a ho.-e,or flexible tube connecting ,to a receiver not shown from which the air is partially exhausted by a pump or other suitable means not shown.

The device is provided with a handle preferably hollow and forminga part of the air conduitfrom the dust collecting device to the receiver.

Referring to the drawing herewith forming; a part ofthis specification, and to the parts indicated by numerals, Figure'l is a side view, partly in sectionon the line u qt in Fig. 2 of one of inyin'iproved dust col lecting devices for manual use. Fig. a bottourview of the same device showingjhe disposition of the tubes and brushes on the inclosed or operating area of the implement. 1, is a casing preferably rounded at the top having a hollow extension 2 that serves as a handle for an operator and to which is attached a hose 3 that connects to a receiver and air exhausting apparatus of the usual kind. 4 indicates a plate having a number of Specification of Letters Patent.

perforations, iii-each of whichis inserted the top of a. flexible tube 5 and a ring of bristles 7 surrounding said tube, each rim of bristles being thus spaced from the other rings. The plate 4 when inserted in the casing 1 forms a chamber 8, common to all the tubes so that air is forcibly drawn through the latter into this chamber 8, and from there through the nipple-or handle-Q and hose as before explained. The tubes 5 are preferably made of some'inaterial that will bend or spring to accommodate uneven surfaces on which they may pass and then These tubes,

them, so that in passing over surfaces to be cleansed the brushes 7 will come just. in contact with and dislodge the dust particlesso these may be drawn into the tubes 5 and expelled as explained. I The implement shown being cylindrical in form will reach into corners except a small area and pass over nearly all the surfaces requiring cleansing. n

The disk or brush plate 4 is held in the casing l by means of screws 9 and can be interchangeable with brushes of different lengths and stiffness as the motive of the work may demand. I

\Vhilc in' the drawingsonly a single form of brush is shown, it is evident the shape may be varied according to the article to be cleaned, and the purpose for which the brush is to be used. as for instance for walls, shelves. pigeon-holes. and the like.

Having thus described the motive and ob jects of-my invention and manner of applyaud desire in a dust removing innjilement, a casing at the bottom. a brush plate ren'iovably "secured within said casing, and having a plurality of perforations therein, and a flexible and a ring of bristles surrounding said tube secured at the top in each perforation. whereby said rings of bristles are spaced from each other, suli stantially as 'described.

In testimony whereof I aiiix my signature
